I had a Docker nightmare debugging Project S on someone's machine. The main issue related to files not being found or noticed by Docker.
The PHP code, when copied over in the docker file, was given to the user
www-data, as configured by the Dockerfile. Additionally the docker
application was run as this user.
However, and here's the issue, the vendor folder (where composer packages
are installed) was owned by root for some reason and did not give write
permission to anyone else. Therefore the docker container was unable to
install additional packages there, causing confusion.
If you're getting "file not found" errors but you see the files, it's probably a permissions issue.
